Thanks for joining this thread, SelenaD ,

You'll want to pull up two separate reports to see the custom field (invoice price plus) and the cost of the item. The internal note you've added is part of the transaction. On the other hand, the cost is for your product and service.

That being said, you can run the Product/Service list report and filter it to see the cost. And, pull up the Invoice list statement and add the internal note field to include it.

Let me show you how

1. Go to Reports from the left menu.
2. Enter Product/Service list and Invoice list in the search field.
3. On the Product/Service List Report page, click the Gear icon and mark the Cost box.
   
4. On the Invoice List by Date Report page, click the Gear icon and mark the internal note box.
   
5. Click Run report to refresh the page.

Then, export those reports to Excel and combine columns from there to get the data you need.
